The line of fire was close now, but Slone did not fear that.
At his shrill whistle Nagger bounded toward him, obedient, but snorting, with ears laid back.

He halted.

A second whistle started him again.

Slone finally dug himself out of the sand, pulled the lassoes out, and ran the length of them toward Nagger.

The black showed both fear and fight.
